Adjustable bed frame construction

A bed frame member adapted to extend transversely between a pair of further bed frame members positioned in spaced parallel relationship, and be retained in one of a plurality of selected positions, comprising:

• a first elongated element having first means adjacent one end for fastening said first element to one of said further bed frame members, said first element including first and second generally perpendicular flat legs;
• a second elongated element having second means adjacent one end for fastening said second element to the other of said pair or further bed frame members and including first and second generally perpendicular flat legs;
• a plurality of longitudinally spaced apertures in one of said first legs, each aperture corresponding to one of said selectable positions;
• a protrusion on the other of said first legs and engageable within one of said apertures for retaining said elements against longitudinal movement in both directions relative to one another when like legs of said first and second elements are positioned in surface-to-surface adjacency with respect to one another;
• and cooperating locking means for retaining said elements against separation when a position has been selected and the legs of said elements are positioned in surface-to-surface adjacency with respect to one another, said locking means including a plurality of longitudinally spaced threaded openings in said first leg of said first element, each opening being associated with one of said apertures and corresponding to one of said selectable positions, the spacing between each threaded opening and its respective aperture being the same, a threaded opening in the first leg of said second element and having the same diameter as the threaded openings in said first leg of said first element, the thread in said opening in said first leg of said second element being partially stripped, and a releasable locking member comprising a screw means having a partially stripped thread received in said opening in said first leg of said second element to permanently mount said screw means on said second element, said screw means being engageable with the threads in one of said openings in said first leg of said first element for retaining said first and second elements against separation, and said screw means being spaced from said protrusion by a distance equal to the spacing between each threaded opening and its respective aperture.
